Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
67+52+x=180
119+x=180
x=61
hope this helps!
the equation to be used would be x=180-(67+52)
Answer:
59°
Step-by-step explanation:
6² + 5² = 61
√61 = 7.810249676
cos(D) = 4 ÷ 7.810249676
4 ÷ 7.810249676 = 0.51214752
cos⁻¹(0.51214752) = 59.19301887
this is rounded down to 59°
Answer:
x = ln 10
Step-by-step explanation:
You meant e^x - 1 = 9. Let's isolate e^x, by adding 1 to both sides. We get:
e^x = 10
Now make use of the property ln a = b <=> a = e^b
Then e^x = 10 becomes
x = ln 10
